opciones de discontinuidad del eje pfg

Question

¿Hay alguna manera de establecer la longitud de la discontinuidad en el eje x? Aquí está el código que he usado:

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
  thick,
    black,%Set the color of the main axes and numbers
    scale=0.389,
    axis lines=left,
    xmin=200,
    xmax=350,
    ymin=0,
    ymax=3,
    major tick length=1.5pt,
    minor tick length=1pt,
    tick align = inside,
    axis x discontinuity=crunch,
    legend cell align={left},
    legend style={anchor=north, draw=none},
    label style={font=\tiny},
    tick label style={font=\tiny},
] 
\end{axis}
\end{tikzpicture}
\end{document}

La figura sale así, con el marcador de discontinuidad que ocupa casi una unidad.

Me gustaría tener un marcador de discontinuidad más corto, como el de la imagen de abajo.

¡Gracias por la ayuda!

Esto esun posiblesolución. Si existe una solución mejor, no lo sé. En

                % this group employs several temporary dimension registers
                % and is therefor scoped:

Cambié

\def\discontstyle{decoration={zigzag,segment length=8pt, amplitude=3pt}}%
\advance \disend by -12pt

que originalmente estaba enpgfplots.code.tex

\def\discontstyle{decoration={zigzag,segment length=12pt, amplitude=4pt}}%
\advance \disend by -16pt
